Just that really - husband and I love good food, children are not especially fussy but would want something more than chicken nuggets and chips, then we've got the parents who have various requirements and preferences and are likely to freak out completely if the place is too fancy/expensive (even though I will be paying).
Basically somewhere that can provide plain enough food (and preferably in small portions) to keep the oldies happy without those of us who enjoy our food feeling like we're in a motorway service station.
Staying central/New Town but can travel, all suggestions welcome!
